ILM - Return on investment (ROI) > Data classification and storage cost - Pg. 99

detailed knowledge of storage device utilization to be easier to plan storage capacity and growth. We describe in the next sections some facts to improve storage return on investment. 5.6.1 Data classification and storage cost After reclaiming space by deleting invalid files and extra versions of duplicated files, the ROI is demonstrated with: Additional space on existing storage using the delta between the actual and future utilization of existing storage. Reduce the utilization of actual storage, and thus reduce the amount of disk storage space needed to be purchased. Data on storage with the appropriate quality of service and cost. Enterprise storage resources are used for critical data only and their reclaimed space is used for critical data growth or new critical applications. Recoverability, availability, and accessability of enterprise storage data are alll improved, because invalid data is not consuming critical storage tier space. 5.6.2 Data management and personnel cost An important element for calculating ROI in an ILM solution relates to application outages, in particular, how much of these outages are due to the problems caused by the difficulty of managing storage. The cost of the outages is measured in terms of revenue, profit, or savings lost due to downtime. In many organizations, between 10 to 20 percent of outages are related to problems with storage management, for example, application outages caused by no free space. With ILM techniques, manual effort is reduced for functions such as: Gathering the storage-used information and analyzing it Planning and implementing new applications that require significant amounts of storage Moving and migrating data Planning for storage growth Going server to server to individually manage storage The reduction of manual effort can be done by investing in: Better tools that make it easier to create new storage for new applications or make it automatically. Ability to move and migrate data nondisruptively, virtualizing storage and defining policies to automatically migrate data among storage tiers. Manage server data from a centralized point. Centralize access to storage. These techniques will strongly improve return on investment, reducing storage personnel cost and application and storage downtime. 5.6.3 Long-term retention and non-compliancy penalties cost The first step in a company's compliance efforts should be to assess the effectiveness of its current internal controls and information management processes. Identification of risks and controls and evaluation of the effectiveness of these controls are important processes for organizations that need to be compliant to regulations. Some non-compliancy penalties Chapter 5. An ILM quick assessment 99
